TfL Ref: 2576-1617

Thank you for your request received by Transport for London (TfL) on 21 March 2017 asking for information about A2 average speed cameras, Blackwall Tunnel - Dartford Heath (distances between cameras).

Your request has been considered in accordance with the requirements of the Freedom of Information Act and our information access policy.  I can confirm that we hold the information you require.

Please see attached.

Please note that in accordance with TfL’s obligations under the Data Protection Act 1998 (DPA) some personal data has been withheld, as required by section 40(2) of the FOI Act. This is because disclosure of this personal data would be a breach of the DPA, specifically the first principle of the DPA which requires all processing of personal data to be fair and lawful. It would not be fair to disclose this personal information when the individuals have no expectation it would be disclosed and TfL has not satisfied one of the conditions of Schedule 2 of the Data Protection Act which would make the processing ‘fair’.

If this is not the information you are looking for,  please do not hesitate to contact me.

Please see the attached information sheet for details of your right to appeal as well as information on copyright and what to do if you would like to re-use any of the information we have disclosed.

Yours sincerely

Sara Thomas
